Debug physical layer characteristics your MIL-STD 1553 faster
differential 1-Mbs MIL-STD 1553 serial widely used today broad range aerospace/defense systems including aircraft avionics equipment, space-based systems, well many ground-based military vehicles. until now, capturing measuring electrical characteristics MIL-STD 1553 signals been difficult tedious process using conventional analog digital oscilloscope. Setting scope trigger synchronize specific transmitted words often required external synchronization signal guessing specific trigger hold-off setting. then determine contents captured displayed communication packet/word required commonly used visual "bit-counting" technique, which slow prone errors. those days over.

uniquely trigger specific Command Status Words, "Remote Terminal Address Bits" triggering mode used. Bits" refers times through which bits that follow remote terminal address (RTA) field. example, triggering specific Command Word usually accomplished specifying format, then transmit/ receive plus sub-address binary format. Figure shows example triggering Command Word with 15dec (0FHEX), transmit/receive high, with sub-address equal 17dec 10001 XXXXX). With this combination "RTA Bit" triggering, scope triggers desired Command Word that requesting data from specific remote terminal. this case, that Status Word from remote terminal (RT) follows this particular Command Word expected.

MIL-STD 1553 Eye-diagram Mask Testing
With addition Agilent's mask testing option (Option LMT) your InfiniiVision series oscilloscope, also perform automatic pass/fail eye-diagram mask tests your MIL-STD 1553 serial bus. Eye-diagram testing used broad range today's serial applications. eyediagram basically overlay digitized bits that shows when bits valid. This provides composite picture quality system's physical layer characteristics, which includes amplitude variations transmission line affects, reflections, system noise, over-shoot, ringing, signal edge placement shift, jitter. Figure shows MIL-STD 1553 eye-diagram mask test input remote terminal (RT). scope repetitively captures overlays Manchester-encoded bits every Data Word received input test points specific remote terminal. Notice that some lower amplitude signals received input this remote terminal failing mask test. This indicated waveform areas highlighted that cross through pass/fail mask. Although mask limit standards/specifications have been established MIL-STD 1553 differential signals, Agilent created diamond-shaped polygon mask limits based existing zero-crossing-distortion input specification minimum voltage swing input specification transformer-coupled systems direct-coupled systems. Since MIL-STD 1553 serial based Manchester bi-phase encoded data transmission, there actually "eyes" separate masks each shown Figure With this type data encoding, signal edge transitions should occur near point each field times through should never signal remain high remain extending across this pair half-bit masks. Since 3-bit synchronization field does adhere Manchester encoding, these particular bits each word tested. addition performing system eye-diagram mask testing every received Data Word, Agilent provides variety MIL-STD 1553 mask files testing specific Command Status Word transmissions received different input test points your system. Figure shows example testing Command Words transmitted from Controller received Remote Terminal with equal 0FHEX. following mask files downloaded from Agilent's website charge

Segmented Memory acquisition captures stores more MIL-STD 1553 words
Segmented Memory acquisition option (Option SGM) Agilent's InfiniiVision Series oscilloscopes optimize your scope's acquisition memory, allowing capture more MIL-STD 1553 Command, Status, Data Words while using less memory. Segmented memory acquisition optimizes number MIL-STD 1553 words that captured consecutively selectively ignoring (not digitizing) unimportant idle time between words. with minimum picoseconds time-tagging resolution, will know precise time between each captured word. Figure shows MIL-STD 1553 measurement with scope trigger Status Words with 0FHEX. Using this trigger condition with segmented memory acquisition mode turned scope easily captures 2000 consecutive occurrences this word total acquisition time seconds. After acquiring 2000 Status Words, then scroll through words individually look anomalies errors. Agilent's InfiniiVision Series oscilloscopes only scopes market today that capture, store, decode MIL-STD 1553 communication traffic using Segmented Memory acquisition.
